Yeah. who-let-rip-smiley.png

Over and over I keep seeing this scenario (not just on OCN):

1: My HDD is failing, what should I do?
2: Run some tool to fix the problem on the drive (like chkdsk or regenerator)
3: It's been busy now for 12 hours...
4: I aborted it (or it finished on its own)
5: The drive doesn't seem to work at all now, how do I recover my files?
6: No further helpful responses.

Instead of something like this:

1: My HDD is failing, what should I do?
2: Are your files backed up?  If so, buy a replacement drive and restore your backup to the new HDD.  You're done.
3: No?  Hurry, image the drive now before it stops working altogether.  Don't modify the disk or its contents in any way.
4: It successfully finishes imaging the disk after 29 hours.  There are 24 MB of corrupted data in the 500 GB image file.
5: The user successfully recovers their data from the disk image using Gizmo and Recuva.

    I keep saying this over and over again, and I'll say it again: If your HDD is failing, you're working with a ticking time-bomb.  You really don't know what is going to set it off, except that disk writes are the fuse.  Run a program that modifies the disk in any way (I'm looking at you, chkdsk), and you're putting a match to the fuse, and the time-bomb is guaranteed to go off sooner, not later.  Please stop giving advice that will cause people to lose their files.  I've successfully recovered files from quite a few ailing HDDs, and I know what I'm talking about!
    I also zero the drives after imaging them (for privacy), and many fail immediately from those writes (they start giving the click of death and zeroing cannot be completed).  However, a couple of failing HDDs have survived being zeroed.  Some of these also lost all their bad sectors and now seem to be working perfectly.  One of these actually survived a user's stupidly running chkdsk.  Chkdsk didn't fix the drive, but zeroing it did; and running chkdsk surface scan on the newly zeroed and formatted found no bad sectors.

You are wrong, HDDs are ticking time bomb even when brand new. never trust any of them and trying repairs before the full backup just puts more stress on them and make them fail earlier. The bigger they are, the harder they fall (fail), applies to them too. Well in any case they have great magnets in them, so at least some loss can be.recouped.
There are 2 types of bad sector. Software ones usually caused usually by bad cables or sudden loss of power and hardware ones, caused by mechanical damage and crashing of heads. First ones could be repaired by Regenerator, some other programs or by zeroing the drive. Hardware ones can not be repaired but with some luck, if SMART catches them early enough, could be relocated to a spare area all of them have. That's the case if only a spot on the platter is damaged, but if the head is damaged only very expensive forensic work can get data back. Then there are also electronic circuit failures where repairs are obvious. Placing of strong magnets on or close to the drive can also wreck havoc with drives.
Ugh knowing all that (and there's more) can make one paranoid enough and really sorry a backup was not made in time. SMART feature, although usually wrong about how long a HDD would last, is good indication of what's going on within the drive and large count of week and relocated sectors spells trouble. Anybody concerned about the drive's health should periodically check on that aspect. HDD Sentinel is just fine tool for that. Relaying on just a good make of HDD is not enough, there's NO infallible HDD, even "professional" server drives.
So be afraid, very afraid for your important data. A bit late to backup is just too late. Throw a Murphy's low or two inn, here and there and with all that, without a timely backup your data is doomed, sooner or latter.
Have a nice day (or nightmare )
